kevinveenbirkenbachandClaude Opus 5.5 778c18fb23 perf(constructor): carry the applications SPOT into the bootstrap roles
The constructor parked no applications carrier between the merge block
and the token store, so every lookup in the svc-swarm-node, svc-storage,
svc-registry and svc-virt bootstrap rendered the SPOT cold, 25 to 30 s
each on a loaded host.

A carrier there was unsafe: in swarm, svc-storage-nfs-server mounts the
NFS export over the controller's DIR_VAR_LIB, so the tokens file the
render reads can appear in the middle of that section, and the cache key
did not notice. merged_applications_cache_key now includes the tokens
file's path, mtime and size, as the users cache key already did, so a
carrier rejects itself once the tokens change. A carrier parked after
the add_host tasks then serves the bootstrap roles. It is parked only in
swarm mode: in compose the section runs in about a second, so a carrier
there would add a render without saving one.

In a swarm drill of web-app-prometheus up to the known NFS probe-write
failure, "Resolve the NFS server backend flavor" went from 29.6 s to
0.07 s, "Probe-mount the NFS export" from 26.4 s to 0.4 s, "Mount
cluster-shared infinito state on controller" from 23.7 s to 0.5 s and
"Ensure Docker-In-Docker DNS works" from 30.0 s to 3.6 s; the run to
that point took 768 s instead of 1735 s.

Closes #925
